Gear-Type Umbrella Runner

ABSTRACT

The invention provides a gear-type umbrella runner. A pentagonal handle is configured on the runner; a gear is configured inside the runner; the handle is coaxially connected with the gear; the gear is connected with the pull rod; the movement of the pull rod is driven by the rotation of the gear. The gear-type umbrella runner of the invention features simple structure, low manufacturing cost and ease and convenience in use. It is applicable to all fields that need runners, especially to parasol umbrella.

FIELD OF THE INVENTION

The invention belongs to the field of parasol umbrella and specificallyprovides a gear-type umbrella runner.

BACKGROUND OF THE INVENTION

Runners and poles are coordinately used in many fields, especially inthe field of parasol umbrella. Traditional runners are designedrelatively moving along poles in the means of pushing or pulling. Thepushing and pulling structure is quite complicated, costs more tomanufacture and brings no user friendliness while in use.

SUMMARY OF THE INVENTION

In view of the problems in the prior art, the invention provides agear-type umbrella runner.

The claimed gear-type umbrella runner, wherein a handle is configured onthe runner; a gear is configured inside the runner; the handle iscoaxially connected with the gear; the gear is connected with the pullrod; the movement of the pull rod is driven by the rotation of the gear.

The claimed gear-type umbrella runner, wherein a spring is configuredbetween the pull rod and the internal side wall of the runner.

The claimed gear-type umbrella runner, wherein the handle is in apentagonal shape.

The gear-type umbrella runner of the invention features simplestructure, low manufacturing cost and ease and convenience in use. It isapplicable to all fields that need runners, especially to parasolumbrella.

BRIEF DESCRIPTION OF THE DRAWINGS

FIG. 1 is a schematic diagram of a gear-type umbrella runner.

FIG. 2 is an internal structure diagram of a gear-type umbrella runner.

Wherein: 1. pole; 2. runner; 3. handle; 4. pull rod; 5. gear; 6. spring.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring now to the drawings, the invention is further described as:

As shown in FIG. 1 and FIG. 2, a gear-type umbrella runner is provided.A pentagonal handle 3 is configured on the runner 2; a gear 5 isconfigured inside the runner 2; the handle 3 is coaxially connected withthe gear 5; the gear 5 is connected with the pull rod 4; the movement ofthe pull rod 4 is driven by the rotation of the gear 5; a spring 6 isconfigured between the pull rod 4 and the internal side wall of therunner 2. The gear 5 can be connected with the pull rod 4 in all regularmeans, for instance, by configuring a compatible tooth on the pull rod 4to engage the gear 5, or connecting the gear 5 with the pull rod 4through a poke block or a connecting rod, and etc. While in use, simplyrotating the handle 3 to drive the rotation of the gear 5 and themovement of the pull rod 4 to move away from the positioning hole in thepole 1 can enable the runner 2 to slide relatively to the pole 1;positioning can be realized by simply moving the runner 2 to therelevant position to enable the pull rod 4 to be ejected by the resetspring 6 into the positioning hole in the pole 1.

The forgoing are some preferred embodiments of the invention which,however, is not limited to the embodiments. The changes, equivalentmodifications and improvements that fall within the true spirit andscope of the invention shall be covered by the invention.

What is claimed is:
 1. A gear-type umbrella runner, wherein a handle (3)is configured on the runner (2); a gear (5) is configured inside therunner (2); the handle (3) is coaxially connected with the gear (5); thegear (5) is connected with the pull rod 4; the movement of the pull rod(4) is driven by the rotation of the gear (5).
 2. The gear-type umbrellarunner as recited in claim 1, wherein a spring (6) is configured betweenthe pull rod (4) and the internal side wall of the runner (2).
 3. Thegear-type umbrella runner as recited in claim 1, wherein the handle (3)is in a pentagonal shape.
